| Abstract: |
A new and distinct variety of Grandiflora rose plant is provided which continuously and abundantly forms fully double long lasting blossoms bearing an attractive combination of red, orange, yellow, and pink tones. The vegetation is very vigorous and the plant exhibits an upright and bushy growth habit. Good winter hardiness and above-average resistance to diseases have been observed. The new variety is particularly well suited for service as attractive ornamentation in parks and gardens. |
| Claim: |
We claim:
1. A new and distinct variety of Grandiflora rose plant characterized by the following combination of characteristics:
(a) forms in abundance on a continuous basis attractive long-lasting fully double blossoms which exhibit brilliant coloration comprising a combination of red, orange, yellow, and pink tones,
(b) exhibits vigorous vegetation,
(c) exhibits an upright and bushy growth habit,
(d) exhibits good winter hardiness,
(e) exhibits above-average resistance to diseases, and
(f) is particularly suited for growing in parks and gardens;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of Grandiflora rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., theseed parent) of the new variety was the Berolina variety (nonpatented in the United States). The male parent (i.e., the pollen parent) was an unnamed seedling (nonpatented in the United States). The parentage of the new variety can be summarized asfollows:
The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.
It was found that the new variety of Grandiflora rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance on a continuous basis attractive long-lasting fully double blossoms which exhibit brilliant coloration comprising a combination of red, orange, yellow, and pink tones,
(b) exhibits vigorous vegetation,
(c) exhibits an upright and bushy growth habit,
(d) exhibits good winter hardiness,
(e) exhibits above-average resistance to diseases, and
(f) is particularly suited for growing in parks and gardens.
The new variety well meets the needs of the horticultural industry and forms attractive ornamentation in the landscape.
The new variety has been found to undergo asexual propagation by a number of routes at West Grove, Pa., including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be stable and to be strictlytransmissible by such asexual propagation from one generation to another.
The new variety has been named the Poulbero variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two yearsof age and were observed during September while budded on Rosa froebelli understock when grown outdoors at West Grove, Pa.

DETAILED DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two-year old plants made during September while budded on Rosa froebelliunderstock and growing outdoors at West Grove, Pa. The coloration in common terms sometimes precedes reference to the chart.
